Function 5 M
A block may contain one or more of the functions listed in the table. Each block
must begin with a block number. If several functions are to be programmed in
one block, they must be programmed in the order shown in the table. Each
function may appear only once in a given block and must be followed by at least
one <space>. Every block must be terminated with <1>.
The N function (block number)
The first function in a block, the N function, specifies the block number. This block
is mandatory, and consists of the letter "N", followed by a number comprising up
to three digits in the range 0 to 999.
Block numbers may appear in any order, and may be used more than once within
a traversing program.
The blocks are always processed in the order in which they are written in the
traversing program.
